I've been adding chunks to Informix using the incorrect size
to fully use a disk partition. I am going to start using the
correct size now (and correct the old ones at a later date).

Now I have 2Gb raw disk partitions. If I want to add an additional
chunk to a dbspace do I set the block size as 1024000 to fully use
the filesystem?

Hope someone can help.

If I understand you correctly.......8-)

In order to use the full 2G rawspace as a chunk for a dbspace, you
would use something like . . .
onspaces -a (some dbspace_name) -p (path to raw disk
partition) -o 0 -s 2048000

This would add a 2G chunk to a dbspace. Remember, onspaces uses K,
not pages.

John - what about onmonitor?

Ooooooh, good point . . . . I haven't used onmonitor in ages....

According to the onmonitor screen I see in 9.30, it shows KB for
offset and size.

2097150 in fact.

It would add somewhat less than 2GB. The full size is (from memory)
2097150K.

If you try too big a number it'll tell you the actual maximum. You'll
probably have to deduct 1 - 3k to make the figure it tells you a
multiple of page size.
